Application filed August 8,1904- Serial No. 219,851-

To 11]] III/mm, it may concern:

Be it known that I. GEORGE W. KIRKPAT- RICK. of Rochester, in the county of Monroe and State of New York, have invented certain in conjunction with those fitted with pneu matic or other resilient tires such as are employed upon motor-driven vehicles for the purpose of increasing the traction or driving action of the wheels when the vehicle is traveling over road-beds having unstable surfaces and. further, to prevent the wheels from skidding or slipping sidewise when the vehicle is traveling over slippery pavements or when the wheels encounter impediments thereon,

such as ruts, street-car tracks. or the like.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a transverse sectional view showing a section of a wheel rim or felly and a tire thereon, illustrating the construction and operation of a device embodying my invention. Fig. 2 is a plan view showing a portion of the inside of the rim or felly and illustrating the manner of securing the device thereto. Fig. 3 is a detail plan view of one of the links composing the band or cincture. Fig. 4 is a sectional view thereof, taken on the line 4 of Fig. 3; and Fig.

5 is a view similar to Fig. 1, illustrating a similar device embodying a'modification of my invention Similar reference-numerals in the several figures indicate similar parts.

of pneumat'ic tire 3, to which is applied the attachment embodying my invention. In the present instance this consists of a band or oincture extending over the tread portion and the sides of the tire, which is formed by a plurality of flat chain-links -I, the end ones thereof engaging securing members in the form of bolts 5 and 6, which are adjustable upon a saddle arranged within the rim of the wheel, so that the band may be drawn or tightened to any desired degree upon the tire. In the illustration the chain-links l are of that particular type known as driving or conveyer chains, having the open rectangular body portion composed of the parallel side bars 7 and the forward and rear cross-bars or ends 8 and 9, respectively, the former of which com prises a hook adapted to removably interlock with the cylindrical rear end of the adjacent link. The band, composedof a pluralityof these chain-links, will be provided at one end with a hook 8*, which engages in an .eye 10, formed upon the securing member while its opposite end is provided with an aperture into which the hook 11 on the. member 6 projects to engage the rear end bar 9 as shown in Figs. 1 and 2.

In order to form a hearing or support for the securing members. I provide a saddle, located within the circumference of the rim or felly 1 and preferably adapted to rest upon the inner surface thereof, which is composed of sectionslZ and-13,havinglips 12' l3'.adapted to extend over the sides of the. rim 1 and to engage therewith when said sections are adjusted relatively to each other by means of screws 14. with perforated ears or lugs 15, through which the members or bolts 5 and 6 pass and which are arranged at slight angles to their respec tive saddle-sections, so as to pitch the attaching ends of the bolts or members outwardly. as shown, so that the end of the band orcincture will be drawn down tightly when the bolts are set up by the nuts 50 and 6'0, which may be in the form of thumb-nuts. lt is not essential that both of the members 5 and 6 be- The sections are each provided the wheel, enabling the coFfwpcrating parts to be quickly applied wl'ienever their use is desired.

The band or cincture may be formed simply by a plurality of the chain-links before described; but as the curved hooked ends form projections which are out of alinement with their side bars 7 their extensive use is liable to. injure the surface of the tire when they unavoidably engage stones or other hard projections which mav be encountered upon a road-bed. To avoid this ditticulty,l pro vide on the inner sides of each of the links bearing-plates 16, having the ends extending beyond the outer edges of the links, which are curved or rounded, as shown at 17, and provided with the edges 18, which embrace the side bars 7 of the links. These bearing-- plates are concaved trair *ersely 'and are formed of such a depth that when the band is applied in operative positionits inner surface will praclrlcall form a con tinuous curved face over the tread portion of the tire. as shown in Fig. l. T rounded ends and extending beyond the edge of the links will prevent the latter from abrading the tire if during the rotation of the wheels the attachment engages an obstruction which would tend either to shift the position of the band or to lift one of its edges away from the tire, as might occur in certain instances if the latter becomes slightl deflated or the band should become loosened. in addition to the bearing-plates I also provide some of the links with wear-plates having bases 19 fitting between the side bars '7 of the links and provided with ribs 20, the ends of which extend over them, as shown, particularly in Figs. and 4c. plates to their respective links consists of a rivet 21, having a shoulder which engages the inner side of the bearing-plate 16 and provided at its ends with heads, as shown, which are upset to firmly secure the parts in place, the provision of the shoulder 22 being for the purpose of preventing the rivet from being driven through the bez-iring-plate into engagement with the tire in case its outer head should become worn away or otherwise removed. T he ribs 20 on the wear-plates extend transversely of the band, so that they not only form good grim'iing devices, but will also clear themselves of mud and other plastic material which is more or less adhesive.

In Fig. 5 l have illustrated the invention embodying a modilical form of a saddle, in which the latter consists of the single piece 23, resting against the rim or fell) 1 and provided with an inwardly extendin curved P1 shoulder 2 1, z'ulapted to embrace one side of The means for attaching these ne bearing-plates having the saddle of relativel adjustable parts it may be readily applied to rims or follies of various widths, and the band or cincture being eomposed of links or jointed sections makes it flexible, allowing'it to accommodate itself to all themovements of atire, and, furthenthesc sections being detachable and interchangeable the length of the band may be readily in creased or decreased to accommodate ti 01 greater or less diameter, and, if nee-es v, worn-out sections may be removed ant. cw ones substituted.
